Cleveland Guardians
Although they have not thrown an MLB pitch in 2024, Preston Claiborne threw 1,239 pitches that were tracked by the PITCHf/x system between 2013 and 2017, including pitches thrown in the MLB Regular Season and Spring Training. In 2017, they relied primarily on their Fourseam Fastball (92mph) and Slider (83mph), also mixing in a Change using a Circle Change grip (86mph).
In 2017, compared to other RHP:
Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, has essentially average velo, results in somewhat more groundballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their slider (take this with a grain of salt because they've only thrown 14 of them in 2017) generates an extremely high number of swings & misses compared to other pitchers' sliders and is an extreme flyball pitch compared to other pitchers' sliders. Their change using a circle change grip (take this with a grain of salt because they've only thrown 9 of them in 2017) is basically never swung at and missed compared to other pitchers' changeups, has a lot of backspin, is slightly firmer than usual and results in somewhat more flyballs compared to other pitchers' changeups.
